Application filed May 11,

T all fw hom t may con-cera Be it known that I, CARL DUEKER, a citi. zen of the United States of America., and resident of Cooper Township, vWebster County, Iowa, have invented a new and useful Husking Mechanism for Corn-Harvesting Machines, of'which the following is a specication.

The object of this invention is to provide an improved construction for husking mechanism.

A further ob-ject of this invention is tol provide improvedl means for supporting and spacing husking rollers.

A further object of this invention is toprovide improved means for cushioning one of each pair of husking rollers relative to the other.

A further object of this invention is to provide improved means for receiving and conveying waste products, such as husks, silk and stems, from the husking rollers.

A further object of this invention is to provide improved means for receiving waste products such as husks, silk and stems and shelled corn from the husking rollers and conveying the waste products in one direction andthe shelled corn to the point of deliverv of ear corn from said husking rollers.

A Ufurther object of this invention is to provide mprovedmeans for agitating, positioning and conveying ears of corn o-n anc relative to husking rollers, before, during and following the operation of husking said ears. Y

A further object of this invention is to provide improved means for agitating and positioning' ears of corn on and relative to husking rollers, before, during and following the operation of huslring said ears.

A further objectof this invention is toprovidel an improved construction for' an interchangeable bearing adaptedV for use on either end of any bushing roller.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and. illustrated by the accompanying drawing, in Which- Figure 1 is a plan, Figure 2 is a side ele vation, Figure 3 a. rear elevation and Figure 4 a front elevation of a husking mechanism embodying my improvements. Figure 5 is aplan of the husking, roller assembly and hearings therefor, parts ofthe frame being removed, on the line-# of Figure 2.` Fig` 1920. serial' No. 380,544.

ure 6v is a cross-section on the indicated line` 6-`6 off Figure 1. Figure 7 isgafcross-sec'tion on thefindicat'ed line 7-'-7 ofY Figure 2. Fig; ureS is a detail elevation of a"p1t1i`1"an-.V FigiV ure 9 is a detail vi'eW of a crank shaft. Figure 10 is a perspective of a journal bearing". Figure 11 is a cross-section, on an enlarged scale, on the indicated linel 11-11 of Fig'- ure 1.

In the vconstruction and mounting of the" mechanism as shown the nun'ieralsv 1Q, 11 designate longitudinal beams-and 12, 13 cross-bars of the frame of' a land vehicle; suchk as is described in my companion application filed March 25, 1920',y andv serially numbered 368,705.' Angle-iron standards 14, 1 5 are iXed' to and rise from rear end portions of the beams 10,'11 and carry joui"- nal bearings 16, 17, inv which1 a' counter# drive shaft 18 ismou'nted'. The 'shaft 18is adapted to be driven by sprocket gearing 19 from a I nain shaft suitably located and, in turn, drlvenf by traction or other power of or on the land vehicle. Wooden frame mem-v l other of members 20,' 21 andare/bolted'there`- to adjacent the ends and" lower margins thereof. Hanger-bars 24,25 are formed with angle-hooks 26 on their ends which overhang and are bolted' to the u'pperinarl gins of the members 20, 21 and 'overli'e and are spacedi from the truss-bars22, 23, The

body portions ofthe truss-bars22, 23 andl the Hanger-'bar 24*l are straightybut the body of the hangerbar 25 is formed with arches 27, 27', 28,123 endl to end, thus providingH looped legs 29., 30, 31 adapted to rest on the truss-bar 23. plurality of journal bearings 32, two fo'r eachV h'jusking roller, are mounted in the spaces between thettr'us'sl bars and hanger-bars`r in this instance sin' in each space. Each bearing 32 (Figure 10) is substantially cubical with one edge rounded oil', and is formed with a horizontal hole 33 adapted to receive, and journala shaft, grooves 34, 35 in its top' and bottom, respectively, at right anglesto th`hl`33",

end recesses 36 lbetween and havinga` com# mon axis parallel with the'groove's; and bolt holes 37, 38'011" opposite" sides of-Y the' grooves ranged kparallel with each other between the bars 22, 24, arepivotedin the frame members 20, 21, are threaded between said` rnembers, and extend loosely within the grooves 34, respectively across the bearings 3.2. Bar washers 42, in this instance three in number, vare threaded on thev rods 40, -41 and extend acrossthe adjacent face of bearings 32; expansive springs 43Y being interposedl between said bearings and washers, seated in recesses36 and tending to press the loose bearing to the fixed bearingv of each pair. The tension of the springs 43 may be -adjusted by manual rotation of the rods 40, 41 by a wrench applied to the heads of said rods, thus traveling the bar washers relative to the fixed bearings. Other bearings 32 are mounted between the bars 23, 25 in positions reversed relative to. the mounting above described, the bearings in each pair being arranged with their ro-unded faces adjacent each other and close to or in con-tact with the rounded ends of the arches "V 27, 27 28 28. All of these bearin 's arel relatively loose, those at the sides, within the arches 27', 28 being backed by springs 43 engaging the angle-hooks 26 and seating` in recesses36 in the plane faces of said bearings; the bearings within the arches 27, 28Y

being arranged with their plane faces adjacent and separated by springs 43 having their ends in recesses 36 in said plane faces.

Husking rollers 44, in this instance six in number, are'inounted rigidly on shafts 45 of likel number, and said shafts are journaled in the holes 33 of the bearings 32. rlhe husking rollers 44 are arranged in pairs revolving involutely, are slightly inclined, have their lower (forward) ends adjacent the'bars 23, 25 and their upper (rear) ends spaced from the bars 22, 24 and the bearings between said bars and preferably are formed of wooden cylinders Ahaving spiral grooves in their peripheries and metal fins 46 seated in and projecting substantially one-half their depth from said grooves. Each roller 44 is formed, preferably, with five 'spiral grooves,

. c spirals .-of very vsteepV and a like number of fins 46, each groove and tin extending from endto end of a roller and comprising substantially one-half the circumference thereof, thus providing pitch. The spiral grooves and fins are arranged oppositely on the rollers of each pair.V Each iin is rela- Vtivelythin and broad and has its width dis` posed radially of its roller.v it is the function of the fins 46, extending from end to end of the rollers 44 and arranged in steep Vspiral rela-tion corn'passing (each.) substantially one-half the circumference of a roller,

to engage husks andsilks on snapped ears Y of corn and drawsaid-husks and silks from the ears and betweenthe rollers. The con- Vtinuous andvspiral arrangement of lthe'iins has an advantagexover intermittently-flocated pegs in that the fins may engage husks on an ear at any point withinV the length of the fins and maintain thatv engagement until all the husks are removed. n also, do not penetratefand lremove kernels of corn from the ears. The depressions or troughs formed by and between 'rollers in eachfpair register with depressions 47 bef' tween the arches 27, 27', 28, 28', so that husked ears of corn may pass freely longitudinally of and from said rollers.` End portions of the shafts 45, at the rear of the upper (rear) bearings 32, are connected in pairs by intermeshing gears 48, 49 for .conjunctive rotation of each pair of. rollers 44.

ach shaft (which is journaled in a fixedl bearing 32) is provided on its rear end with The fins,`

Agitators 54 are mounted for rec-ti-v bearings 52, l53, one agitatorfor each pair of slide seats, and extend longitudinally of and above the spaces between pairs ofthe husking rollers 44, and each agitator is formed with a journal eye55 at one end and a fin 56 on and rising from its median line between Vand spaced from, the slide seafts. A crank shaft 57 is journaled in suitable bearings 58 on the posts 14, above and projecting rearwardly from the bearings 15, and is formed with cranks 59, 60 connected by pitinen to the journal eyes 55 on theagitators. ries a sprocket wheel 61, hereinafter referred to, whereby it is driven. A shaft 62 extends loosely through holes in the Vframe members 20,21, crossesrabove the rear end of the roller bed and is journaled at its ends in bearings 63, 64 fixed to said members, and sprocket wheels 65 are carried on said shaft between said members. A shaft 66 is jo-urnaled at its ends in bearings 67, 68 mounted for vertical adjustment on the forward (lower) ends ofthe frame members 20, 21 and smooth flanged wheels 69, 70 are carried by said shaft between saidV frame members; Sprocket chains 71, 72 are The crank shaft 57 car- Cil mounted on the sprockets and ride loosely on the fianged wheels 69, 70, and said chains are connected 4transversely by channel bars 73 extending across the .bed of husking rollers. The chains 71, 72' and channel bars 73 may sag| to and ride at times on the fins `56 of the .agitators The shaft 62 carries a sprocket wheel 74, hereinafterreferredto, .whereby it is driven. It is the function of the agitators to direct the ears (husked orunhusked) into and longitudinally of the troughs formed by and within the-pairs of rollers. It is'the function ofthe conveyor, .formed by the chains 7l, 72 and channel bars '73, to lassist` the -agitators'in placing the ears longitudinally ofthe rollers, and tok feed said ears along the rollers during and following the husking operations. A pan or trough 75, of perforated sheet metal concaved slightly in cross-section, is mounted on the posts 14, is inclined from rear to front, beneath the husking bed, and is adapted to receive shelled corn fromthe'husking rollers and deliver it forwardly to and beneath .the point of delivery of the husked ears. A shaft 76 is journaled in suitable bearings on -the posts 14 beneath and parallel -with the shaft 61 and sprocket wheels 77, 78 are mounted `rigidlI on said shaft 76 in the rear end portion of the pan 75. Stub shafts 79, 80 .are journaledfin suitable bearings 8l adjustab-ly mounted on the Aforward ends of the sides of the pan 7 5,'and flanged. rollers 82 are fixed to 'the inner ends of said shafts: and have their iianges adjacent the bearings. An endless carrier 83 is mounted on and driven by .the sprocket wheels '77, 7 8 and runs loosely around vthe flanged rollers |82, within the pan, the lower portion of said carrier traveling forwardly adjacent to or in cont-acd-I with the perforated bottom of said pan and tending to drag shelled corn forwardly therein to a .point of delivery, the dust and dirt falling through the Vholes in the pan. rThe upper portion of the carrier` 83 travels rearwardly and receives husks, silks,.stems and the like from the husking bed and delivers them at the rear of the machine. The carrier 83 is formed of inter-engaging ywire vslats formed with lateral hooked arms on their ends; and may -be `slackened and disconnected or tightened manually by adjustment of the bearings 81. A sprocket wheel 84 is fixed to one end of and drives *thel shaft 76. A sprocket wheel 85 is fixed to one end of the counter-drive shaft 18. The sprocket wheels 6l, 74, 84 and 85 lie in the same plane, at one side of the machine frame and are connected by a sprocket chain 86 in such manner that the wheel 85 drives the other wheels in turn as indicated by the arrows 'in Figure 2. The pitmen above referred to are designated my numerals 87,

88 .in yFigures 3 and 4 and one. of them is shown in det-ailin Figure 8. `It is formed of a. forked stem or body portion having divided wooden bearing 89 removably and replaceably mounted in its fork and a lateral arm 90. The bearing 89 is adapted to embrace -and pivot on'the journals 91, 92 of the cranks 59, 60. The stems of the pitman are inclinedto the axis of the crank shaft 57 andthe arms 90 pass through and pivot in the eyes 55 of the agitators 54, thus operatively connecting the cranks to the agitators. The arms 90 may be secured to the pitmen by cotter pins or keys 93. Suitable gear connections 94 are provided to connect the counter-drive shaft 18 to and drive suitable elevating mechanism (not shown) .adapted .to receive snapped corn from snapping mechanism and deliver it on the upper rear portion of the `husking bed.
